Computer Advice Please??

There are some videos that I have been wanting to post, but it seems that I can no longer watch things on youtube. There is no error message. The video screen just never loads; a commercial will play if there is one in front of the video, but the actual video that comes after will not. Any advice?

I can’t post any of the videos I want because I can’t view them to make sure I’ve posted the right one. Baaaaaaa! Technology is frustrating!
